I bought this today on a whim, and i love it. It is true that the formula dries out your skin, however.
What everyone needs to understand is that the sebum your skin naturally produces is meant to keep your skin hydrated and ward off infections. When you use facial cleansers to strip the oil off of your face daily, your skin constantly loses it's natural protective barrier.
That being said, I am not against having a shine-free face, in fact I like me oil-less myself. But you need to be replenishing the moisture in your skin as you take it away. Your body is an amazing thing, your face will start producing more and more sebum to counteract the losses. So moisturizing your face ultimately will keep your skin less oily due to your body not freaking out like "AHHH need more sebum!"
This isn't a miracle cure-all, but I know it works for me: I use Argan Oil on my face (and hair) in the morning after cleansing and at night. Not sure how it would work for anyone else, but my skin absorbs it all after about ten minutes, and this keeps my face from producing too much oil during the day. I was skeptical at first about putting oil on my face to combat another oil, but it works. I read it on a website and gave it a go. It's also helped with my acne scars and discolorations but once again, not a cure-all, and it's only helped just enough to be noticeable to myself. Note: I have oily skin.
Hope I've helped!
